DRIVING AXLE OF CROSS-COUNTRY VEHICLE Russian patent published in 2007 - IPC B62D63/02 B60K17/00 

FIELD: transport engineering.

SUBSTANCE: proposed driving axle of cross-country wheeled vehicle has housing rigidly connected to frame and including final drive with differential to drive axle-shafts passed through holes in frame sidemembers and coupled with axle-drive units mounted for angular displacement in vertical direction with wheels whose hub units are coupled with frame through levers and independent suspension. Housing is attached to lower surfaces of frame cross-members, and its ends are brought out through holes in sidemembers. Corrugated cup fitted on each end of housing is connected by other end on sidemember from inner side. Suspension is made in form of semispring arranged square to sidemember, one end of spring being secured on sidemember or cross-member of frame, and other end, on hub unit of wheel. Semispring consists of leavers of different length placed one onto the other in stack, with high elastic material linings being placed between spring leaves and rigidly connected with said leaves. Spring leaves are made of composite material of reinforced plastic type. Bracket with ball support for connection with wheel hub unit is secured on end of semispring by glue or bolted joint.

EFFECT: improved service characteristics, reduced weight of unspring mass.
